Serial No. 440,272.

To all whom it may concern:

Be it known that I, VALTER H. GAMBLE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Force- Feed Lubricators; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in force feed lubricators.

T he object of the invention is to provide a lubricator of this character having a plurality of oil discharging ports from which oil is successively forced.

A further object is to provide a lubricator having means to regulate the quantity of oil discharged therefrom.

W ith these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be described and particularly pointed out in the appended claims.

In the accompanying' dra-wings, Figure l is a horizontal sectional view of a lubricator constructed in accordance with the invention; F ig. 2 is a vertical sectional view on the line 2-2 of Eig. l; Fig. 3 is a similar view on the line 3 3 of Fig. l; Fig. 4 is a similar view on the line 1-4 of Fig. l; Fig. 5 is a side view of the lubricator casing with the pump casing and chamber removed, and showing` the arrangement of the oil suction ports; E ig. 6 is a vertical transverse sectional view of the lubricator and pump casings taken on the line 6 6 of Eig. l, with the working parts removed; Fig. 7 is a detail perspective view of the inner section of the pump; Fig. 8 is a similar View of the outer section; Fig. 9 is a detail view of one side of the pump operating star wheels, showing the manner in which the. same is operated; Eig. l() is a similar view of the opposite side showing the manner in which the wheel is locked against movement in either direction; F ig. Il is a detail view of the clutch for regulating the position of one of the star wheel operating devices; and l2 and 13 are detail views of the clutch con trolling star wheel operating device for the star wheel of the inner pump section.

In the embodiment of the invention I provide a lubricator casing, l, which is here shown and is preferably rectangular in shape and has on one side a circular iiange or seat, 2, to which is adapted to be bolted or otherwise secured a pump casing, 3, in which is formed a circular pump chamber, A. In the pump chamber, at, is arranged a rotary pump consisting of an outer section, 5, and an inner section, 6.

The outer pump section, 5, consists of a circular disk, 7, on one side of which, adjacent to its edge, is formed an annular flange, 8, which incloses a circular space, 9, in which the inner section, G, of the pump is adapted to operate. In the flange 8 is formed a radially projecting recess, l0, which extends to near the outer edge or circumference of the flange, as shown. One of the radial walls of the recess, l0, is notched as shown at 12, and in said notched portion and through the disk 7 is formed a suction port 13. In the outer wall of the recess l0 is formed an elongated discharge passage or port, 14, which is adapted to be brought into communication with a series of discharge ports, l5, formed in the edge of the pump casing, 3, as shown. lith the discharge ports 15 are adapted to be con-A nected leads for conveying the oil to various parts of the machine to be lubricated. The disk 7 of the outer pump section is provided with a centrally `disposed tubular shaft, 16, the passage of which extends through the disk 7, as shown.

The inner section of the pump consists of a circular disk or plate 17, the diameter of which is substantially the same as the circular space, 9, formed by the fiange 8 of the outer pump section, The disk, 17, of the inner pump section is adapted to work in the space, 9, and on said disk is formed a radially projecting wing, 18, which is adapted to work in the recess 10 of the iiange, 8. One edge of the wing 1S is offset or formed at an angle as shown at 19 to engage and tit into the notched wall, 12, of the recess, 10, and when so engaged, the wing, 18, will cover the suction port, 13, in the plate, 7, and the slot, 14, in the outer wall of the recess, l0. The suction port, 13, in the plate, 7, of the outer pump section is adapted to be brought into alinement with a series of suction ports, 20, formed in the adjacent wall of the lubricator casing and communicating with an annular oil pocket, 2l, which is supplied with oil from a suitable reservoir 21, arranged on the lubricator cas ing. The lower portion of the oil pocket, 21, is provided with a drain port, 2lb, which is normally closed by a screw plug, 21C.

The disk or plate, 17, of the inner pump section 6 is provided on one side with a centrally disposed. laterally projecting shaft, 22, which, when the plate, 17, is in an ope 1ative position in the space, 9, will project through the tubular shaft, 16, of the outer pump section.

The shafts 16 and 22 of the outer and inner pump sections project through a bearing passage, 23, formed in the adjacent side ofthe lubricator casing. The shaft, 22, of

the inner-pump section extends through the lubricator casing and has its opposite end mounted in a suitable bearing, 24, formed in the opposite side of the casing, as shown. The shaft, 16, of the outer pump section eX- tends into the casing to near the center of the same. The shaft, 22, of the inner pump section is provided with a longitudinally disposed passage, 25, the outer' end of which communicates with a vent, 26, formed in the end of the bearing, 24, of the lubricator casing. The opposite end of the passage, 2:3, communicates with radially disposed passage, 27, formed in the plate or disk, 17, of the inner pump section, and communicating at its outer end with the space, 10, formed in the flange, 8, of the outer pump section, whereby the air in said space between the wing, 1S, and the lower wall of said space, is permitted to pass out as said wing is moved toward the lower wall of said space, thus preventing` the air from compressing and forming an obstruction to the movement of the wing, 1S, and the inner pump section.

On the tubular shaft, 16, of the outer pump section, and adjacent to the pump side of the lubricator casing, is fixedly mounted a star wheel, 28, said wheel consisting of a disk having on one side a series of laterally projecting lugs, 29, between each of which is formed a radially disposed passage, 30, the purpose of which will hereinafter appear. On the opposite sides of the star wheel disk is formed a series of radially disposed locking ribs, 31, said ribs being arranged exactly opposite to or in line with the passages, 30, on the opposite side of the disk. There may be any suitable number of passages and ribs formed on the star wheel, 2S, the same being here shown as provided with eight ribs, and corresponding passages. The wheel, 2S, is provided with a centrally disposed hub, 32, which projects inwardly on the tubular shaft of the outer pump section.

On the shaft, 22, of the inner pump section is tixedly mounted a star wheel, 33, which consists of a disk having on one side a series of laterally projecting lugs, 34, between which are formed radially disposed passages, 35. On the opposite side of the disk is formed a series of radially disposed locking ribs, 36, arranged directly opposite or in line with the passages on the opposite side of the disk. The star wheels, 28 and 33, are of the same construction, the star wheel 28 being provided to intermittently operate the. outer pump section, while the star wheel, 83, is provided to intermittently operate the inner pump section.

The star wheels and pump section are operated from any suit-able moving part of the machine to which the lubricator is applied,

or by any other suitable power, and the means for transferring the motion of said movable part to the star wheels will now be described.

In the lower portion of the lubricator casing and preferably in the center thereof is mounted a worm shaft, 37. The shaft, 37, eXtends through the casing and has its inner end journaled in a suitable bearing, 38, formed in one side of the casing, while its opposite end is mounted in a packed bearing, 39, on the opposite side of the casing. On the outer end of the shaft, 37, is arranged a band wheel, 40, with which is adapted to be engaged a suitable operating belt or band which eXtends to a moving part of the machine or other source of power. On the shaft, 37, is formed a worm 41, which is engaged with a worm wheel, 42, fiXedly mounted on a shaft', 43, which extends through the lubricator casing parallel to the pump shafts, 16 and 22. On the end of the shaft., adjacent to the star wheel, 28, is fixedly mounted a sleeve, 44, on one end of which is arranged a radially projecting disk having on its inner side a laterally projecting, annular locking rim or flange, 45, in which is formed a gap or space, 46, into which the ribs 31 of the star wheel, 28, are adapted to enter to permit the star wheel to turn. On the adjacent side of the worm wheel, 42, is mounted a star wheel operating roller, 47, which, when the worm wheel is revolved, is adapted to engage the passages 30 between the lugs 29 on the star wheel, 28, and thereby revolve said star wheel and the outer section of the pump to which said star wheel is attached one-eighth of a revolution. The roller, 47, is arranged directly in line with the gap, 46, in the locking rim so that when the roller, 47, engages one of the passages, 30, in the star wheel, the corresponding rib, 31, on the opposite side of the star wheel will simultaneously engage the gap, 46, in the locking rim, thereby permitting said star wheel to turn. As soon as the roller 47 has turned the star wheel oneeighth of a revolution and passed out of the passage, 30, the cylindrical surface of the rim 45 will be brought to a locking position between two of the ribs, 81, thereby holding the star wheel against' further movement until the roller, 47, has again reached a position to engage the next passage, 30, of the wheel.

On the end of the worm gear shaft, 113, adjacent to the star wheel, 33, is loosely mounted a sleeve, 4:8, the outer end of which projects into a bearing opening, 49, formed in the adjacent wall of the lubricator casino, as shown. Qn the sleeve, 48, preferably at its inner end is formed a radially projecting crank arm, 50, on the outer end of which is mounted a laterally projecting roller, 5,1, which is adapted to be engaged lwith the passages, 35, in the star wheel, 33, and to turn said star wheel, and the inner section of the pump to which it is connected, oneeighth of a revolution. On the sleeve, e8, adjacent to the side of the casing is arranger` a disk having' an inwardly projecting, annular flange or rib, 52, which is provided with a gap or passage, with which the ribs, 86, of the star wheel are engaged to permit said wheel to be turned by the roller, 51, on the crank arm 50.

The sleeve, a8, is loosely mounted on the shaft of the worm gear to provide for the adjustment of the roller, 51, whereby the movement of the star wheel, 33, is regulated to vary the time and distance of the movement of the inner pump section, whereby a greater or less amount of oil will be drawn through the suction ports, 13 and Q0, in the outer pump section and the adjacent wall of the lubri ator casing before said port 20 is cut off by the movement of the outer pump section. ln order to lock the sleeve, 48, on the worin gear shaft and to hold the arm 50 and roller, 51, in their adjusted position, I provide a. clutch collar, 54, which is adapted to be slipped onto the outer end of the worm gear shaft, 48, which projects beyond the end of the sleeve, Lt8, and through the bearing, 19, in the side of the lubricator casing. i removable cap, is provided to cover the clutch collar, 54, and the ends of the shaft, 48, and sleeve, 48, said cap preferably having a screw-threaded engagement with the side of the casing, as shown. On the end of the sleeve, 48, is formed a longitudinally projecting locking lug or toot-h, 56, which is adapted to engage with one of a series of locking notches, 57, formed in the inner end of the clutch collar, l54. The collar is provided with a square bore or passage which receives the squared end of the shaft l-B, when the collar is placed thereon so that by turning the collar to different positions before placing the same on the squared end of the shaft, the positions of the notches will be varied so that the locking lugs or teeth, 56, on the sleeve, Lt8, may be caused to engage whichever notch in the clutch gives the desired adjustment to the crank arm, 50, and roller, 51, to cause the star Wheel to operate the inner section of the pump at the proper time with respect to the movement of the outer section thereof by the star Wheel, 28, in the opposite side of the lubricator casing.

When it is desired to change the position of the sleeve 4-8 to adjust the arm, 50, and roller, 51, it is simply necessary to unscrew the cap, 55, from the side of the casing and with the fingers remove the clutch colla 541, from the squared end of the shaft and turn the same to the proper position for bringing the desired notch, 5T, therein, into engagement with the lug or tooth, 55, on the end of the sleeve, 48. In the side of the worm gear, 4i, adjacent to the crank arm, 5t), are arranged stop pins, 58, which are placed a suitable distance apart, and are designed to limit the adjustment of the arm, 50, and thus prevent the same and the roller, 51, from being moved out of operative position with respect to the passages, of the star wheel, 83.

ln the operation of the device, assuming the parts of the pump to be in the position shown in Fig. 3 of the drawings, wherein the suction and discharge ports, 13 and 1T', of the outer pump section are covered by the wing, 18, of the inner pump section, said pump section and wing begin to rotate in the direction shown by the arrow, therebj/v uncovering the suction ports 121 and also (mening the discharge port, le, and causing the oil from the oil pocket, 21, to flow through the ports, 20, of the lubricator casing, with one of which the port 13 always registers'` and the suction port, 18. As soon as the port. 18, opens, the oil flows by suction and gravity into the constantly enlarging space between the angular wall, 19, of the wing, 18, and the adjacent wall, 12, of the space, 10, while the air in the space on the opposite side of the wing is forced out through the passages 2T and 25 in the inner pump section and its shaft and is discharged through the vent, 96, in the side of the casing, thus preventingl the air from compressing in this space. The wing, 18, continues to rotate until stopped by the lower wall of the spacel 10. at which time the outer pump section begins to move in the pump casing through its operating mechanism. Both pump sections nov: move together and the port 18 is thereby moved out of aliuement with the port, Q0, in the lubricator casing with which it previously registered. After the port 13 has thus been moved out of alinement with 'he port, Q0. the discharge port, 14, will be brought into alinement with one of the discharge ports, 15, formed in the edge of the pump casing, thereby causing the oil in the passage, 10, to pass out of said port and into the lead connecting therewith by which it is conducted to the parts of the machine to be lubricated.

rthe operating parts of the device are so arranged that when the discharge port, 14-`r in the outer pump section reaches the next .l OO

adjacent discharge port, 15, in the pump casing, the inner pump section will be locked against further movement, while the outer pump section will continue to move around until the notched wall, 1'2, of the pas-lage, 1t), is again brought into engagement with the angular edge, 19, of the wing, 18, thereby closing the space on this side of the wing and forcing all of the oil theretiii'ough out tln'ougli the discharge port, 15, as hereinbefoi'e desci'ibed. This cycle of operations is i'epeated for each set of ports, and the oil is thereby delivered to each bearing` oi' pai't of the machine to which the l ads from the discharge ports, 15, are connected.

From the foregoing description, falten in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction, may be resorted to Without departing from the principle or sacrificing any of the ad van- 'ages of the invention as defined in the appended claims.
